Using SCPI commands to configure digital I/O lines
Using SCPI commands to configure digital I/O lines:
To set the line mode to the specified line, send the following command:
:DIGital:LINE<n>:FUNCtion <function>
Where <n> is the digital line and <function> is line mode. For details, see the following table.
Line mode
Description
AUTO
When applied each line with AUTO mode, it represents:
 Line 1: Trigger in
 Line 2: Meter complete output
 Line 3: Fault output
 Line 4 to line 6: Not available.
MOUTH
Manual output high
MOUTL
Manual output low
MINPut
Manual input
If you apply AUTO to digital I/O line from 4 to 6, it results an error 507, "Pins 4 to 6 don’t support
function AUTO for single channel instrument."
You can also read the digital I/O line by sending the command:
:DIGital:line<n>:MANual:INPut:DATA?
Where <n> is the digital line.
Only when the digital I/O line is set to manual input, sending this query command will return the
value. Otherwise, the instrument generates an error 508, "Querying manual input data of the line
which is not set as Manual Input line."
